Questions

Phone Battery Rotation With Recharge Times

$29

There were a total of four questions, three of which I had seen in interview write-ups. One question I hadn't encountered before was: your phone is out of battery, but you need to use it for t minutes, and you have a set of backup batteries with capacities = [2, 3, 4, 5], and each battery has a corresponding recharge time = [12, 8, 9, 10]. For example, if you need to use it for t = 100 minutes, once the first battery capacity[0] is depleted, you switch to the next one, and then capacity[0] starts recharging, taking 12 minutes to fully charge. You continue this process until you've used up t. If you can use it for the required time, return the total number of fully charged batteries used; if not, return -1. I couldn't solve it, so I continued with the onsite. Looking for some credits, thanks!
